In this work, a new kind of 2-pyrazoline compound with azastilbene on position 5 has been synthesized. The photoinduced cis-trans isomerization and its mechanism have also been studied. Results indicate that the rate for the photoisomerization reaction of the title compound depends strongly on the polarity of solvents used, and the photoisomerization reaction led to increase of the fluorescence intensity of this compound with increase of irradiation duration.
- 1,3,5-triaryl-2-pyrazoline,
- Fluorescence quantum yield,
- Photoinduced cistrans isomerization,
- Intramolecular photoinduced charge transfer
